The expert from Germany, made a presentation (GRSP-54-28) of the workshop held in Bergisch Gladbach (16 July 2013), Germany, aimed at defining a procedure for the test position of the Biofidelic Rear Impact Dummy (BioRID II). He added that as a result of the workshop, experts agreed that the use of the Head Restraint Measuring Device (HRMD) was no longer needed for static assessment and BioRID positioning. He concluded that test procedures and injury criteria would likely be finalized in the next meeting of the IWG scheduled for 4-6 February 2014 in Brussels. The expert from the United Kingdom introduced, for information, the latest stage of the draft UN GTR (ECE/TRANS/WP.29/GRSP/2013/24) and a draft Addendum 1 (GRSP-54-05) to the Mutual Resolution No. 1 (M.R.1). He explained that a revised official proposal of UN GTR would be submitted by the IWG at the May 2014 session of GRSP as well as a final draft addendum to M.R.1.

The expert from United Kingdom introduced GRSP-68-23, representing the development of Mutual Resolution No. 1, Addendum 1 and concerning the Biomechanical Rear Impact Dummy-II (BIORID-II) UN dummy as part of test tools in UN GTR No. 7 and UN Regulation No. 17 (10 series of amendments) for use in rear impact assessment. He recommended that consideration on this proposal would be made together with GRSP-54-05 (Draft addendum 1 to M.R.1), introduced at the fifty-fourth session of GRSP (see ECE/TRANS/WP.29/GRSP/54, para. 4). He recommended GRSP to provide comments on GRSP-68-23 and GRSP-54-05 before 31 January 2021 for consideration in the final document to be submitted to the May 2021 session of GRSP. It was noted that copyrights were expected to be removed from drawings when the proposal would be finally adopted by WP.29 and AC.3. GRSP agreed with the recommendation of the expert from the United Kingdom and agreed to resume discussion at its May 2021 session.

The expert from United Kingdom of Great Britain and Northern Ireland introduced ECE/TRANS/WP.29/GRSP/2021/2 and GRSP-69-39 (this last correcting typo errors) through GRSP-69-01 as proposal for Addendum 1 to Mutual Resolution No. 1 (Specifications for the Construction, Preparation and Certification of the 50th percentile male Biofidelic Rear Impact Dummy, anthropomorphic test Device (BioRID-II UN). He explained that the structure of the proposal was stemming from GRSP-54-05 (Draft addendum 1 to M.R.1), introduced at the fifty-fourth session of GRSP (see ECE/TRANS/WP.29/GRSP/54, para. 4) and that the body of the proposal introduced the general design of the dummy, including the essential dimensions and how they are checked. He added that the text associated with the procedures for dismantling, assembling and adjusting the dummy had received editorial review and that proprietary names had been removed. It was noted that copyrights were expected to be removed from drawings when the proposal would be finally adopted by WP.29 and AC.3. He finally urged GRSP to recommend the proposal to allow a thorough implementation of UN Regulation No. 17 and UN GTR No. 7 by Contracting Parties of both Agreements. The experts from the Netherlands, Germany, Japan, France agreed with the recommendation of the expert from the United Kingdom of Great Britain and Northern Ireland. The expert from the United States of America endorsed in principle the proposal, however, she explained that a full technical review of the document was not completed by her Administration and requested a time reservation.
